"stair stepping"

Stair stepping..., I know what it is, but I am unable to get it to see what it looks like. Any suggestions?

What camera are you using, Frank? If it has a sharpness control, try adjusting it. It can sometimes mask the edges. High contrast scenes are your best bet. I get them everytime I shoot a bird on a telephone wire, that is against a white sky or is somewhat back lit. On my product shots I get them on the edges of knives, forks and spoons. What are you using to view the footage? If I turn the sharpness, detail way down the edges will smooth out and you loose the stair stepping.

Thanks. I've tried the bird on the wire thing. I'll try it again, though. I have the DVL9500s and MX300s.

Don't get me wrong here. I'm trying to get stair stepping so that I can see what it looks like on my cams.

stair stepping is seen on a line ( edge of object) that runs at a angle ( like a 45% angle ) in your frame .... if you move in ( zoom in with editing software) the line will NOT be straight - it will look like the side view of STAIRS ( the kind you walk up/down = stair stepping) ..also you can see it easy in a CIRCLE.

the bird on wire will work, just make sure you compose the frame so the wire is running at a 45% angle in the frame NOT a 180% horizontal or 90% vertical ....

Thanks. I'll try this tomorrow, and play it back on my TV, via AV-out. The reason why I want to do this is so that I can avoid stair stepping when I do some serious shooting. So far, I've been lucky.

Frank, I think you'd be better off to watch the footage on a high
resolution monitor or on your NLE editing system. TV has a
tendency to more mask such issues. A monitor tends too be much
sharper (especially LCD screens, for example the one on my laptop)

Thanks. Today I did try to get this, but couldn't see any S.S. I'll have to pop the tapes in my buddy's portable Sony deck tomorrow.
